This invention relates to a water closet in which complete flushing takes place even when the flushing water is supplied slowly.

In order that an effective flushing will take place in water closets now used, the .flushing water must enter them at a rate ot 1.5 to 2.0 liters per second. The water is brought to the'c'loset either from a iushing cistern or through a flushing valve. In

order that the requisite speed ofthe flushing water shall be attained if the former is the case the flushing cistern must be placed at a sufficient height above the closet, depending upon the dimensions of the flushing pipe, and in the latter case the piping to the Hushing valve must be given sufiiciently large dimensions. In a closet, according to the present invention, the flushing takes place quite independently of the speed with which the flushing water enters the closet.

The invention is principally characterized therein, that at or above the upper edge Vof that part of the outlet pipev which is enlarged into a collecting funnel is arranged a special cistern, the flushing water cistern, which entirely or partly surrounds the upper edge of the funnel vand whose inner wall situatedagainst the funnel, or a part thereof, is movable and arranged to co-operate with a tightening device so, that in one position of the wall or part ot' the wall, all the flushing water supplied through a floatvalve, flushing valve or any other suitable way collects in the flushing water cistern, which thereby is completely closed from the funnel and outlet, and in another position of the movable wall 'or part of the wall the flushing water cistern is opened, so that all the flushing watervfiows over the upper edge of the funnel and' along its inner sides, thereby giving a thorough and effective llushing to all the parts in the'closet that require rinsing.

An important characteristic of the water closets according to this invention is, that all the flushing Water supplied through a float valve, flushing Valve or the like, and which will be used for the flushing is collected in a iushing Water cistern arranged in the closet itself, which cistern is situated at or above the upper edge of that part orn the outlet pipe which is enlarged into a collecting funnel, whereby all the flushing water, when the closet is used, is caused to flow from the flushing. water cistern over the flushing cistern joined to said inlet.

upper edge oi' the funnel and along its inner sides, thereby causing a most effective flushing.

In the accompanying drawing is shown an embodiment of a water closet according to this invention. Fig. l. shows a vertical section ot the closet with the different parts in that position, they assume when the closet is not in use, whereby the flushing water cistern is empty. Fig.-2 shows the upper part of the same closet with the movable part of the seatpressed down and the lioat valve opened, so that the flushing water may flow into the u shows the upper part of the closet with the movable part ot the seat still pressed down. The needed amount of flushing water having entered the flushing water cistern, and the Heat valve being closed.

lu the upper part of the closet l a cistern 2, the fiushing water cistern, is arranged around the upper edge l of that part of the outlet pipe which is enlarged to form a collecting tunnel 3, above which the cistern is situated. The inner wall 5 of the flushing water cistern situated towards the collecting funnel is formed out of a movable ring 6 in the closet, the closing ring, of the same shape as the upper edge 4- oi' the collecting' funnel. The closing ring 6 is provided with a tightening' ring 9 and is supported by springs 8, which normally hold the samein such a position, that the tightening ring` 9 is not in touch with the upper edge of the collecting funnel, as shown in Fig. l, whereby a ring shaped outlet canal l0 from' the flushing water ciste-rn 2 -is formed. At those iiushing water cistern. Fig. 3r

times when the closing ring 6 is pressed down, as shown in Figs. 2 and 3, said canal is closed. In the flushing Water cistern there is a wall l1 with a number of holes 12. The flushing water reaches the flushing water cistern 2 in the closet 1 through an inlet 13 from a float valve, iushing valve, or The seat consists as usual of two parts, the stationary part let and the movable part 16, which parts are joined together by a hinge 15,-the part 14: being fastened by screws to the closet l. y n

The described water closet works in the following manner. kWhen one sits down on the movable part 16 of the seat, the closing ring 6 is pressed down, whereby the springs 8 are compressed, see Figs. 2 and 3. Tight-l
